Same specifications as ADS7807P, U.
NOTES: (1) LSB means Least Significant Bit. One LSB for the
±
10V input range is 305
μ
V. (2) Typical rms noise at worst-case transition. (3) As measured with
fixed resistors, see Figure 7b. Adjustable to zero with external potentiometer. (4) Full-scale error is the worst case of
–
Full-Scale or +Full-Scale untrimmed deviation
from ideal first and last code transitions, divided by the transition voltage (not divided by the full-scale range) and includes the effect of offset error. (5) This is the
time delay after the ADS7807 is brought out of Power-Down mode until all internal settling occurs and the analog input is acquired to rated accuracy. A Convert
command after this delay will yield accurate results. (6) All specifications in dB are referred to a full-scale input. (7) Usable bandwidth defined as full-scale input
frequency at which Signal-to-(Noise + Distortion) degrades to 60dB. (8) Recovers to specified performance after 2
FS input overvoltage. (9) The minimum V
IH
level for the DATACLK signal is 3V.
